I think thats the point. you tried with a koz hair which was a .cr2 hair. theres no problem, because cr2 can take matposes without problems. aila hair by DAZ is a .hr2. (a prop). and props only takes matposes if they are parented to a figure. so you cannot use matposes at a hair which is load without a figure. if you load the figure first, and then the .hr2 hair it is parented und you can change the colour with matposes. :)
